I've been playing this the last few days and it's great. Getting it for free from psn plus is wonderful too. I think a game like this works perfectly for the new plus program. One, it gets a lot more people playing a game that came out months ago. Two, if you can't wait to level up you can spend real money and unlock some stuff early, which gives the game makers more money. Three, the people who bought the game when it came out and have been playing the whole time, I think I saw a guy at level 600, have a huge group of newbies to crush.
I have already gotten the $50 worth for my year. I like the idea of more "free" games and micro charges for people who want to go through them faster.
